This is an auscultation example of a mid-systolic click heard at the mitral valve area.
The first and second heart sounds are normal . The second heart sound is unsplit and no murmur is present so that you can concentrate on the systolic click.
On the anatomy tab you can see that the mitral valve posterior leaflet prolapses. The mid-systolic click is produced by the sudden prolapse of the leaflet.
A mid-systolic click is often followed by a late systolic murmur of mitral valve leaflet prolapse.
